  The presence of multiple phases/ components within a nanocomposite material impacts the properties of a nanomaterial. Therefore, there is a need to estimate the phase fraction of each component present in a sample. Spurr-Myers proposed a valuable formula for estimating the rutile and anatase phase fraction ...  Read More ...

Mayyadah H. Mohsin; Khawla S. Khashan; Ghassan M. Sulaiman; Khalil A. A. Khalil

Volume 3, Issue 3 , September 2023, Page 20-36

  A technique for exfoliating Boron nitride (BN) nanosheets was devised, which was then followed by a laser ablation-fragmentation process to produce lamellar hexagonal Boron nitride nanostructures (h-BNNs). The physicochemical properties of the nanoparticles were analyzed to investigate the effect of ...  Read More ...
